Stuff in pittsburgh, because the musing thread was killed
A couple of cool places to check out:
The Incline, this is pretty much a pully car that runs up and down Mount Washington, at the top you are able to look over the entire city it is a pretty amazing view, and the incline only costs like $2. http://incline.pghfree.net/
If you are into art, there is the Andy Warhol museum, featuring all sorts of sweet Warhol images and other various exhibits. http://www.warhol.org/
If you really are into art check out the mattress factory there http://www.mattress.org/
University of Pittsburgh is obviously in Pittsburgh, the Cathedral of Learning is a pretty sweet thing to see. Looks cool from the outside, and inside, there are different rooms reflecting different cultures. http://www.emporis.com/en/wm/bu/?id=121991
